DETROIT — Karl Zimmermann cites 1.5 million potential reasons to justify his $7 million investment in a car wash and detail center at his dealership in the Detroit suburb of Redford. That's how many cars and trucks cross a busy intersection next to his store, Matick Chevrolet, each week.
The twin-tunnel automatic wash is scheduled to open next month on the 13-acre dealership site. Its 140-foot conveyors and 15 indoor detailing bays will be convenient for dirty cars passing by.
